Wire Rod Uncoiler Machines



Machine equipment is specifically designed to reduce the downtime of large wire preparation required for large diameter wire feeding. The equipment includes RGO series automatic wire rod unwinder with a straightening mechanism and RGV series sharpening unit for the front end of the wire rod coil. This equipment can work as part of a production line for wire drawing together with the RCD series inverted vertical drawing machine.

Application & advantages of automatic wire feeding & shaving machine

Machine equipment is specifically designed to reduce the downtime when feeding wire rod of large diameters. Main advantages of RGO / RGV series devices:

  • Traditional preparation time is approx. 30 minutes with pointing work; however using this equipment, the preparation time can be reduced down to 6 minutes.
  • From auto-feeding to pressing and striking, straightening, wire shaving, and then to Die end - all tedious work will be performed semi-automatically.
  • Wire shaving treatment process is automated with no physcial involvement of the operator with the wire rod. Contrary to the conventional method where the operator is always at risk of accident due to physcially holding the wire during pointing.
  • This automated machine equipment greatly increases production efficiency by up to 5 times by shortening wire rod preparation time.

Coil Pay-Off Stand with Coil Opener Unit

360 degree Circumgyration Coil Pay-off stand

Three types of motorized Wire Rod Uncoiler Machine are optionally available with the Combined Wire Drawing Machine:

  • 90 degree Tilt-able Coil Pay-off stand.
  • 360 degree Circumgyration Coil Pay-off stand.
  • Combined Wire Rod Decoiler that can tilt 90 degrees and rotate 360 degrees.
  • Equip with the track and sensor, which can stop the pay-off stand and combined drawing machine simultaneously.
  • Loading weight of Coil Pay-off stand: max. 3 ton.
  • Pay-off Stand can turn over by 90 degree angle / rotate 360 degrees.
  • Oil box including motor.

Coil Opener

To pull the coil into the straightening roller by robot arm. Then, straight the end of coil by rotating rollers. Before the coil enters the drawing die, the beginning of the coil should be reduced the diameter to pass the drawing die.

The coil opener can pull out the end of large diameter wire coils quickly and easily. The crooked part of wire will pass through the straightening rollers and be straightened.
